Drew, I like my #5 Parker try gun better than any of the others because the grip area is not disturbed by the mechanism. Even the #4 Curtis (looks like a Smith from the Woodward style Prince of Wales grip shape) has mechanism in the grip. The $18,000 Lefever is like my Parker with an undisturbed grip area. This mechanism is unneccesary because my #5 Parker can be adjusted for cast and offset without a mechanism in the grip. I think you may have pictures of my Parker from Patrick Lein. The pictured Smith was probably made at a time when Curtis was not superintendent at Hunter Arms because it doesn't seem to be a Curtis design.
